INTRODUCTION TO JOE MULLER

Joseph Muller, Secret Service detective of the Imperial Austrian police,
is one of the great experts in his profession. In personality he differs
greatly from other famous detectives. He has neither the impressive
authority of Sherlock Holmes, nor the keen brilliancy of Monsieur Lecoq.
Muller is a small, slight, plain-looking man, of indefinite age, and of
much humbleness of mien. A naturally retiring, modest disposition, and two
external causes are the reasons for Muller's humbleness of manner, which
is his chief characteristic. One cause is the fact that in early youth a
miscarriage of justice gave him several years in prison, an experience
which cast a stigma on his name and which made it impossible for him, for
many years after, to obtain honest employment. But the world is richer,
and safer, by Muller's early misfortune. For it was this experience which
threw him back on his own peculiar talents for a livelihood, and drove him
into the police force. Had he been able to enter any other profession, his
genius might have been stunted to a mere pastime, instead of being, as
now, utilised for the public good.

Then, the red tape and bureaucratic etiquette which attaches to every
governmental department, puts the secret service men of the Imperial
police on a par with the lower ranks of the subordinates. Muller's
official rank is scarcely much higher than that of a policeman, although
kings and councillors consult him and the Police Department realises to
the full what a treasure it has in him. But official red tape, and his
early misfortune... prevent the giving of any higher official standing to
even such a genius. Born and bred to such conditions, Muller understands
them, and his natural modesty of disposition asks for no outward honours,
asks for nothing but an income sufficient for his simple needs, and for
aid and opportunity to occupy himself in the way he most enjoys.

Joseph Muller's character is a strange mixture. The kindest-hearted man in
the world, he is a human bloodhound when once the lure of the trail has
caught him. He scarcely eats or sleeps when the chase is on, he does not
seem to know human weakness nor fatigue, in spite of his frail body. Once
put on a case his mind delves and delves until it finds a clue, then
something awakes within him, a spirit akin to that which holds the
bloodhound nose to trail, and he will accomplish the apparently
impossible, he will track down his victim when the entire machinery of a
great police department seems helpless to discover anything. The high
chiefs and commissioners grant a condescending permission when Muller
asks, "May I do this? ... or may I handle this case this way?" both
parties knowing all the while that it is a farce, and that the department
waits helpless until this humble little man saves its honour by solving
some problem before which its intricate machinery has stood dazed and
puzzled.

This call of the trail is something that is stronger than anything else in
Muller's mentality, and now and then it brings him into conflict with the
department,... or with his own better nature. Sometimes his unerring
instinct discovers secrets in high places, secrets which the Police
Department is bidden to hush up and leave untouched. Muller is then taken
off the case, and left idle for a while if he persists in his opinion as
to the true facts. And at other times, Muller's own warm heart gets him
into trouble. He will track down his victim, driven by the power in his
soul which is stronger than all volition; but when he has this victim in
the net, he will sometimes discover him to be a much finer, better man
than the other individual, whose wrong at this particular criminal's hand
set in motion the machinery of justice. Several times that has happened to
Muller, and each time his heart got the better of his professional
instincts, of his practical common-sense, too, perhaps,... at least as far
as his own advancement was concerned, and he warned the victim, defeating
his own work. This peculiarity of Muller's character caused his undoing at
last, his official undoing that is, and compelled his retirement from the
force. But his advice is often sought unofficially by the Department, and
to those who know, Muller's hand can be seen in the unravelling of many a
famous case.

The following stories are but a few of the many interesting cases that
have come within the experience of this great detective. But they give a
fair portrayal of Muller's peculiar method of working, his looking on
himself as merely an humble member of the Department, and the comedy of
his acting under "official orders" when the Department is in reality
following out his directions.

THE CASE OF THE POCKET DIARY FOUND IN THE SNOW

CHAPTER ONE. THE DISCOVERY IN THE SNOW

A quiet winter evening had sunk down upon the great city. The clock in the
old clumsy church steeple of the factory district had not yet struck
eight, when the side door of one of the large buildings opened and a man
came out into the silent street.

It was Ludwig Amster, one of the working-men in the factory, starting on
his homeward way. It was not a pleasant road, this street along the edge
of the city. The town showed itself from its most disagreeable side here,
with malodorous factories, rickety tenements, untidy open stretches and
dumping grounds offensive both to eye and nostril.

Even by day the street that Amster took was empty; by night it was
absolutely quiet and dark, as dark as were the thoughts of the solitary
man. He walked along, brooding over his troubles. Scarcely an hour before
he had been discharged from the factory because of his refusal to submit
to the injustice of his foreman.

The yellow light of the few lanterns show nothing but high board walls and
snow drifts, stone heaps, and now and then the remains of a neglected
garden. Here and there a stunted tree or a wild shrub bent their twigs
under the white burden which the winter had laid upon them. Ludwig Amster,
who had walked this street for several years, knew his path so well that
he could take it blindfolded. The darkness did not worry him, but he
walked somewhat more slowly than usual, for he knew that under the thin
covering of fresh-fallen snow there lay the ice of the night before. He
walked carefully, watching for the slippery places.

He had been walking about half an hour, perhaps, when he came to a cross
street. Here he noticed the tracks of a wagon, the trace still quite
fresh, as the slowly falling flakes did not yet cover it. The tracks led
out towards the north, out on to the hilly, open fields.

Amster was somewhat astonished. It was very seldom that a carriage came
into this neighbourhood, and yet these narrow wheel-tracks could have been
made only by an equipage of that character. The heavy trucks which passed
these roads occasionally had much wider wheels. But Amster was to find
still more to astonish him.

In one corner near the cross-roads stood a solitary lamp-post. The light
of the lamp fell sharply on the snow, on the wagon tracks, and—on
something else besides.

Amster halted, bent down to look at it, and shook his head as if in doubt.

A number of small pieces of glass gleamed up at him and between them, like
tiny roses, red drops of blood shone on the white snow. All this was a few
steps to one side of the wagon tracks.

"What can have happened here—here in this weird spot, where a cry
for help would never be heard? where there would be no one to bring help?"

So Amster asked himself, but his discovery gave him no answer. His
curiosity was aroused, however, and he wished to know more. He followed up
the tracks and saw that the drops of blood led further on, although there
was no more glass. The drops could still be seen for a yard further,
reaching out almost to the board fence that edged the sidewalk. Through
the broken planks of this fence the rough bare twigs of a thorn bush
stretched their brown fingers. On the upper side of the few scattered
leaves there was snow, and blood.

Amster's wide serious eyes soon found something else. Beside the bush
there lay a tiny package. He lifted it up. It was a small, light, square
package, wrapped in ordinary brown paper. Where the paper came together it
was fastened by two little lumps of black bread, which were still moist.
He turned the package over and shook his head again. On the other side was
written, in pencil, the lettering uncertain, as if scribbled in great
haste and in agitation, the sentence, "Please take this to the nearest
police station."

The words were like a cry for help, frozen on to the ugly paper. Amster
shivered; he had a feeling that this was a matter of life and death.

The wagon tracks in the lonely street, the broken pieces of glass and the
drops of blood, showing that some occupant of the vehicle had broken the
window, in the hope of escape, perhaps, or to throw out the package which
should bring assistance—all these facts grouped themselves together
in the brain of the intelligent working-man to form some terrible tragedy
where his assistance, if given at once, might be of great use. He had a
warm heart besides, a heart that reached out to this unknown who was in
distress, and who threw out the call for help which had fallen into his
hands.

He waited no longer to ponder over the matter, but started off at a full
run for the nearest police station. He rushed into the room and told his
story breathlessly.

They took him into the next room, the office of the commissioner for the
day. The official in charge, who had been engaged in earnest conversation
with a small, frail-looking, middle-aged man, turned to Amster with a
question as to what brought him there.

"I found this package in the snow."

"Let me see it."

Amster laid it on the table. The older man looked at it, and as the
commissioner was about to open it, he handed him a paper-knife with the
words: "You had better cut it open, sir."

"Why?"

"It is best not to injure the seals that fasten a package."

"Just as you say, Muller," answered the young commissioner, smiling. He
was still very young to hold such an office, but then he was the son of a
Cabinet Minister, and family connections had obtained this responsible
position for him so soon. Kurt von Mayringen was his name, and he was a
very good-looking young man, apparently a very good-natured young man
also, for he took this advice from a subordinate with a most charming
smile. He knew, however, that this quiet, pale-faced little man in the
shabby clothes was greater than he, and that it was mere accident of birth
that put him, Kurt von Mayringen, instead of Joseph Muller, in the
position of superior.

The young commissioner had had most careful advice from headquarters as to
Muller, and he treated the secret service detective, who was one of the
most expert and best known men in the profession, with the greatest
deference, for he knew that anything Muller might say could be only of
value to him with his very slight knowledge of his business. He took the
knife, therefore, and carefully cut open the paper, taking out a tiny
little notebook, on the outer side of which a handsome monogram gleamed up
at him in golden letters.

"A woman made this package," said Muller, who had been looking at the
covering very carefully; "a blond woman."

The other two looked at him in astonishment. He showed them a single blond
hair which had been in one of the bread seals.

"How I was murdered." Those were the words that Commissioner von Mayringen
read aloud after he had hastily turned the first few pages of the
notebook, and had come to a place where the writing was heavily
underscored.

The commissioner and Amster were much astonished at these words, but the
detective still gazed quietly at the seals of the wrapping.

"This heading reads like insanity," said the commissioner. Muller shrugged
his shoulders, then turned to Amster. "Where did you find the package?"

"In Garden street."

"When?"

"About twenty minutes ago."

Amster gave a short and lucid account of his discovery. His intelligent
face and well-chosen words showed that he had observation and the power to
describe correctly what he had observed. His honest eyes inspired
confidence.

"Where could they have been taking the woman?" asked the detective, more
of himself than of the others.

The commissioner searched hastily through the notebook for a signature,
but without success. "Why do you think it is a woman? This writing looks
more like a man's hand to me. The letters are so heavy and—"

"That is only because they are written with broad pen," interrupted
Muller, showing him the writing on the package; "here is the same hand,
but it is written with a fine hard pencil, and you can see distinctly that
this is a woman's handwriting. And besides, the skin on a man's thumb does
not show the fine markings that you can see here on these bits of bread
that have been used for seals."

The commissioner rose from his seat. "You may be right, Muller. We will
take for granted, then, that there is a woman in trouble. It remains to be
seen whether she is insane or not."

"Yes, that remains to be seen," said Muller dryly, as he reached for his
overcoat.

"You are going before you read what is in the notebook?" asked
Commissioner von Mayringen.

Muller nodded. "I want to see the wagon tracks before they are lost; it
may help me to discover something else. You can read the book and make any
arrangements you find necessary after that."

Muller was already wrapped in his overcoat. "Is it snowing now?" He turned
to Arnster.

"Some flakes were falling as I came here."

"All right. Come with me and show me the way." Muller nodded carelessly to
his superior officer, his mind evidently already engrossed in thoughts of
the interesting case, and hurried out with Amster. The commissioner was
quite satisfied with the state of affairs. He knew the case was in safe
hands. He seated himself at his desk again and began to read the little
book which had come into his hands so strangely. His eyes ran more and
more rapidly over the closely written pages, as his interest grew and
grew.

When, half an hour later, he had finished the reading, he paced restlessly
up and down the room, trying to bring order into the thoughts that rushed
through his brain. And one thought came again and again, and would not be
denied in spite of many improbabilities, and many strange things with
which the book was full; in spite, also, of the varying, uncertain
handwriting and style of the message. This one thought was, "This woman is
not insane."

While the young official was pondering over the problem, Muller entered as
quietly as ever, bowed, put his hat and cane in their places, and shook
the snow off his clothing. He was evidently pleased about something. Kurt
von Mayringen did not notice his entrance. He was again at the desk with
the open book before him, staring at the mysterious words, "How I was
murdered."

"It is a woman, a lady of position. And if she is mad, then her madness
certainly has method." Muller said these words in his usual quiet way,
almost indifferently. The young commissioner started up and snatched for
the fine white handkerchief which the detective handed him. A strong sweet
perfume filled the room. "It is hers?" he murmured.

"It is hers," said Muller. "At least we can take that much for granted,
for the handkerchief bears the same monogram, A. L., which is on the
notebook."

Commissioner von Mayringen rose from his chair in evident excitement.
"Well?" he asked.

It was a short question, but full of meaning, and one could see that he
was waiting in great excitement for the answer. Muller reported what he
had discovered. The commissioner thought it little enough, and shrugged
his shoulders impatiently when the other had finished.

Muller noticed his chief's dissatisfaction and smiled at it. He himself
was quite content with what he had found.

"Is that all?" murmured the commissioner, as if disappointed.

"That is all," repeated the detective calmly, and added, "That is a good
deal. We have here a closely written notebook, the contents of which,
judging by your excitement, are evidently important. We have also a
handkerchief with an unusual perfume on it. I repeat that this is quite
considerable. Besides this, we have the seals, and we know several other
things. I believe that we can save this lady, or if it be too late, we can
avenge her at least."

The commissioner looked at Muller in surprise. "We are in a city of more
than a million inhabitants," he said, almost timidly.

"I have hunted criminals in two hemispheres, and I have found them," said
Muller simply. The young commissioner smiled and held out his hand. "Ah,
yes, Muller—I keep forgetting the great things you have done. You
are so quiet about it."

"What I have done is only what any one could do who has that particular
faculty. I do only what is in human power to do, and the cleverest
criminal can do no more. Besides which, we all know that every criminal
commits some stupidity, and leaves some trace behind him. If it is really
a crime which we have found the trace of here, we will soon discover it."
Muller's editorial "we" was a matter of formality. He might with more
truth have used the singular pronoun.

"Very well, then, do what you can," said the commissioner with a friendly
smile.

The older man nodded, took the book and its wrappings from the desk, and
went into a small adjoining room.

The commissioner sent for an attendant and gave him the order to fetch a
pot of tea from a neighbouring saloon. When the tray arrived, he placed
several good cigars upon it, and sent it in to Muller. Taking a cigar
himself, the commissioner leaned back in his sofa corner to think over
this first interesting case of his short professional experience. That it
concerned a lady in distress made it all the more romantic.

In his little room the detective, put in good humour by the thoughtful
attention of his chief, sat down to read the book carefully. While he
studied its contents his mind went back over his search in the silent
street outside.

He and Amster had hurried out into the raw chill of the night, reaching
the spot of the first discovery in about ten or fifteen minutes. Muller
found nothing new there. But he was able to discover in which direction
the carriage had been going. The hoof marks of the single horse which had
drawn it were still plainly to be seen in the snow.

"Will you follow these tracks in the direction from which they have come?"
he asked of Amster. "Then meet me at the station and report what you have
seen."

"Very well, sir," answered the workman. The two men parted with a hand
shake.

Before Muller started on to follow up the tracks in the other direction,
he took up one of the larger pieces' of glass. "Cheap glass," he said,
looking at it carefully. "It was only a hired cab, therefore, and a
one-horse cab at that."

He walked on slowly, following the marks of the wheels. His eyes searched
the road from side to side, looking for any other signs that might have
been left by the hand which had thrown the package out of the window. The
snow, which had been falling softly thus far, began to come down in
heavier flakes, and Muller quickened his pace. The tracks would soon be
covered, but they could still be plainly seen. They led out into the open
country, but when the first little hill had been climbed a drift heaped
itself up, cutting off the trail completely.

Muller stood on the top of this knoll at a spot where the street divided.
Towards the right it led down into a factory suburb; towards the left the
road led on to a residence colony, and straight ahead the way was open,
between fields, pastures and farms, over moors, to another town of
considerable size lying beside a river. Muller knew all this, but his
knowledge of the locality was of little avail, for all traces of the
carriage wheels were lost.

He followed each one of the streets for a little distance, but to no
purpose. The wind blew the snow up in such heaps that it was quite
impossible to follow any trail under such conditions.

With an expression of impatience Muller gave up his search and turned to
go back again. He was hoping that Amster might have had better luck. It
was not possible to find the goal towards which the wagon had taken its
prisoner—if prisoner she was—as soon as they had hoped.
Perhaps the search must be made in the direction from which she had been
brought.

Muller turned back towards the city again. He walked more quickly now, but
his eyes took in everything to the right and to the left of his path. Near
the place where the street divided a bush waved its bare twigs in the
wind. The snow which had settled upon it early in the day had been blown
away by the freshening wind, and just as Muller neared the bush he saw
something white fluttering from one twig. It was a handkerchief, which had
probably hung heavy and lifeless when he had passed that way before. Now
when the wind held it out straight, he saw it at once. He loosened it
carefully from the thorny twigs. A delicate and rather unusual perfume
wafted up to his face. There was more of the odour on the little cloth
than is commonly used by people of good taste. And yet this handkerchief
was far too fine and delicate in texture to belong to the sort of people
who habitually passed along this street. It must have something to do with
the mysterious carriage. It was still quite dry, and in spite of the fact
that the wind had been playing with it, it had been but slightly torn. It
could therefore have been in that position for a short time only. At the
nearest lantern Muller saw that the monogram on the handkerchief was the
same in style and initials as that on the notebook. It was the letters A.
L.

CHAPTER TWO. THE STORY OF THE NOTEBOOK

It was warm and comfortable in the little room where Muller sat. He closed
the windows, lit the gas, took off his overcoat—Muller was a
pedantically careful person—smoothed his hair and sat down
comfortably at the table. Just as he took up the little book, the
attendant brought the tea, which he proceeded at once to enjoy. He did not
take up his little book again until he had lit himself a cigar. He looked
at the cover of the dainty little notebook for many minutes before he
opened it. It was a couple of inches long, of the usual form, and had a
cover of brown leather. In the left upper corner were the letters A. L. in
gold. The leaves of the book, about fifty in all, were of a fine quality
of paper and covered with close writing. On the first leaves the writing
was fine and delicate, calm and orderly, but later on it was irregular and
uncertain, as if penned by a trembling hand under stress of terror. This
change came in the leaves of the book which followed the strange and
terrible title, "How I was murdered."

Before Muller began to read he felt the covers of the book carefully. In
one of them there was a tiny pocket, in which he found a little piece of
wall paper of a noticeable and distinctly ugly pattern. The paper had a
dark blue ground with clumsy lines of gold on it. In the pocket he found
also a tramway ticket, which had been crushed and then carefully smoothed
out again. After looking at these papers, Muller replaced them in the
cover of the notebook. The book itself was strongly perfumed with the same
odour which had exhaled from the handkerchief.

The detective did not begin his reading in that part of the book which
followed the mysterious title, as the commissioner had done. He began
instead at the very first words.

"Ah! she is still young," he murmured, when he had read the first lines.
"Young, in easy circumstances, happy and contented."

These first pages told of pleasure trips, of visits from and to good
friends, of many little events of every-day life. Then came some accounts,
written in pencil, of shopping expeditions to the city. Costly laces and
jewels had been bought, and linen garments for children by the dozen. "She
is rich, generous, and charitable," thought the detective, for the book
showed that the considerable sums which had been spent here had not been
for the writer herself. The laces bore the mark, "For our church"; behind
the account for the linen stood the words, "For the charity school."

Muller began to feel a strong sympathy for the writer of these notices.
She showed an orderly, almost pedantic, character, mingled with generosity
of heart. He turned leaf after leaf until he finally came to the words,
written in intentionally heavy letters, "How I was murdered."

Muller's head sank down lower over these mysterious words, and his eyes
flew through the writing that followed. It was quite a different writing
here. The hand that penned these words must have trembled in deadly
terror. Was it terror of coming death, foreseen and not to be escaped? or
was it the trembling and the terror of an overthrown brain? It was
undoubtedly, in spite of the difference, the same hand that had penned the
first pages of the book. A few characteristic turns of the writing were
plainly to be seen in both parts of the story. But the ink was quite
different also. The first pages had been written with a delicate violet
ink, the later leaves were penned with a black ink of uneven quality, of
the kind used by poor people who write very seldom. The words of this
later portion of the book were blurred in many places, as if the writer
had not been able to dry them properly before she turned the leaves. She
therefore had had neither blotting paper nor sand at her disposal.

And then the weird title!

Was it written at the dictation of insanity? or did A. L. know, while she
wrote it, that it was too late for any help to reach her? Did she see her
doom approaching so clearly that she knew there was no escape?

Muller breathed a deep breath before he continued his reading. Later on
his breath came more quickly still, and he clinched his fist several
times, as if deeply moved. He was not a cold man, only thoroughly
self-controlled. In his breast there lived an unquenchable hatred of all
evil. It was this that awakened the talents which made him the celebrated
detective he had become.

"I fear that it will be impossible for any one to save me now, but perhaps
I may be avenged. Therefore I will write down here all that has happened
to me since I set out on my journey." These were the first words that were
written under the mysterious title. Muller had just read them when the
commissioner entered.

"Will you speak to Amster; he has just returned?" he asked.

Muller rose at once. "Certainly. Did you telegraph to all the railway
stations?"

"Yes," answered the commissioner, "and also to the other police stations."

"And to the hospitals?—asylums?"

"No, I did not do that." Commissioner von Mayringen blushed, a blush that
was as becoming to him as was his frank acknowledgment of his mistake. He
went out to remedy it at once, while Muller heard Amster's short and not
particularly important report. The workingman was evidently shivering, and
the detective handed him a glass of tea with a good portion of rum in it.

"Here, drink this; you are cold. Are you ill?" Amster smiled sadly. "No, I
am not ill, but I was discharged to-day and am out of work now—that's
almost as bad."

"Are you married?"

"No, but I have an old mother to support."

"Leave your address with the commissioner. He may be able to find work for
you; we can always use good men here. But now drink your tea." Amster
drank the glass in one gulp. "Well, now we have lost the trail in both
directions," said Muller calmly. "But we will find it again. You can help,
as you are free now anyway. If you have the talent for that sort of thing,
you may find permanent work here."

A gesture and a look from the workingman showed the detective that the
former did not think very highly of such occupation. Muller laid his hand
on the other's shoulder and said gravely: "You wouldn't care to take
service with us? This sort of thing doesn't rate very high, I know. But I
tell you that if we have our hearts in the right place, and our brains are
worth anything, we are of more good to humanity than many an honest
citizen who wouldn't shake hands with us. There—and now I am busy.
Goodnight."

With these words Muller pushed the astonished man out of the room, shut
the door, and sat down again with his little book. This is what he read:

"Wednesday—is it Wednesday? They brought me a newspaper to-day which
had the date of Wednesday, the 20th of November. The ink still smells
fresh, but it is so damp here, the paper may have been older. I do not
know surely on what day it is that I begin to write this narrative. I do
not know either whether I may not have been ill for days and weeks; I do
not know what may have been the matter with me—I know only that I
was unconscious, and that when I came to myself again, I was here in this
gloomy room. Did any physician see me? I have seen no one until to-day
except the old woman, whose name I do not know and who has so little to
say. She is kind to me otherwise, but I am afraid of her hard face and of
the smile with which she answers all my questions and entreaties. 'You are
ill.' These are the only words that she has ever said to me, and she
pointed to her forehead as she spoke them. She thinks I am insane,
therefore, or pretends to think so.

"What a hoarse voice she has. She must be ill herself, for she coughs all
night long. I can hear it through the wall—she sleeps in the next
room. But I am not ill, that is I am not ill in the way she says. I have
no fever now, my pulse is calm and regular. I can remember everything,
until I took that drink of tea in the railway station. What could there
have been in that tea? I suppose I should have noticed how anxious my
travelling companion was to have me drink it.

"Who could the man have been? He was so polite, so fatherly in his anxiety
about me. I have not seen him since then. And yet I feel that it is he who
has brought me into this trap, a trap from which I may never escape alive.
I will describe him. He is very tall, stout and blond, and wears a long
heavy beard, which is slightly mixed with grey. On his right cheek his
beard only partly hides a long scar. His eyes are hidden by large smoked
glasses. His voice is low and gentle, his manners most correct—except
for his giving people poison or whatever else it was in that tea.

"I did not suffer any—at least I do not remember anything except
becoming unconscious. And I seem to have felt a pain like an iron ring
around my head. But I am not insane, and this fear that I feel does not
spring from my imagination, but from the real danger by which I am
surrounded. I am very hungry, but I do not dare to eat anything except
eggs, which cannot be tampered with. I tasted some soup yesterday, and it
seemed to me that it had a queer taste. I will eat nothing that is at all
suspicious. I will be in my full senses when my murderers come; they shall
not kill me by poison at least.

"When I came to my senses again—it was the evening of the day before
yesterday—I found a letter on the little table beside my bed. It was
written in French, in a handwriting that I had never seen before, and
there was no signature.

"This strange letter demanded of me that I should write to my guardian,
calmly and clearly, to say that for reasons which I did not intend to
reveal, I had taken my own life. If I did this my present place of sojourn
would be exchanged for a far more agreeable one, and I would soon be quite
free. But if I did not do it, I would actually be put to death. A pen, ink
and paper were ready there for the answer.

"'Never,' I wrote. And then despair came over me, and I may have indeed
appeared insane. The old woman came in. I entreated and implored her to
tell me why this dreadful fate should have overtaken me. She remained
quite indifferent and I sank back, almost fainting, on the bed. She laid a
moist cloth over my face, a cloth that had a peculiar odour. I soon fell
asleep. It seemed to me that there was some one else besides the woman in
the room with me. Or was she talking to herself? Next morning the letter
and my answer had disappeared. It was as I thought; there was some one
else in my room. Some one who had come on the tramway. I found the ticket
on the carpet beside my bed. I took it and put it in my notebook!!!!!

"I believe that it is Sunday to-day. It is four days now since I have been
conscious. The first sound that I remember hearing was the blast of a
horn. It must come from a factory very near me. The old windows in my room
rattle at the sound. I hear it mornings and evenings and at noon, on week
days. I did not hear it to-day, so it must be Sunday. It was Monday, the
18th of November, that I set out on my trip, and reached here in the
evening—(here? I do not know where I am), that is, I set out for
Vienna, and I know that I reached the Northern Railway station there in
safety.

"I was cold and felt a little faint—and then he offered me the tea—and
what happened after that? Where am I? The paper that they gave me may have
been a day or two old or more. And to-day is Sunday—is it the first
Sunday since my departure from home? I do not know. I know only this, that
I set out on the 18th of November to visit my kind old guardian, and to
have a last consultation with him before my coming of age. And I know also
that I have fallen into the hands of some one who has an interest in my
disappearance.

"There is some one in the next room with the old woman. I hear a man's
voice and they are quarrelling. They are talking of me. He wants her to do
something which she will not do. He commands her to go away, but she
refuses. What does he mean to do? I do not want her to leave me alone. I
do not hate her any more; I know that she is not bad. When I listened I
heard her speaking of me as of an insane person. She really believes that
I am ill. When the man went away he must have been angry. He stamped down
the stairs until the steps creaked under his tread: I know it is a wooden
staircase therefore.

"I am safe from him to-day, but I am really ill of fright. Am I really
insane? There is one thing that I have forgotten to write down. When I
first came to myself I found a bit of paper beside me on which was
written, 'Beware of calling in help from outside. One scream will mean
death to you.' It was written in French like the letter. Why? Was it
because the old woman could not read it? She knew of the piece of paper,
for she took it away from me. It frightens me that I should have forgotten
to write this down. Am I really ill? If I am not yet ill, this terrible
solitude will make me so.

"What a gloomy room this is, this prison of mine. And such a strange ugly
wall-paper. I tore off a tiny bit of it and hid it in this little book.
Some one may find it some day and may discover from it this place where I
am suffering, and where I shall die, perhaps. There cannot be many who
would buy such a pattern, and it must be possible to find the factory
where it was made. And I will also write down here what I can see from my
barred window. Far down below me there is a rusty tin roof, it looks like
as if it might belong to a sort of shed. In front and to the right there
are windowless walls; to the left, at a little distance, I can see a
slender church spire, greenish in colour, probably covered with copper,
and before the church there are two poplar trees of different heights.

"Another day has passed, a day of torturing fear! Am I really insane? I
know that I see queer things. This morning I looked towards the window and
I saw a parrot sitting there! I saw it quite plainly. It ruffled up its
red and green feathers and stared at me. I stared back at it and suddenly
it was gone. I shivered. Finally I pulled myself together and went to the
window. There was no bird outside nor was there a trace of any in the snow
on the window sill. Could the wind have blown away the tracks so soon, or
was it really my sick brain that appeared to see this tropical bird in the
midst of the snow? It is Tuesday to-day; from now on I will carefully
count the days—the days that still remain to me.

"This morning I asked the old woman about the parrot. She only smiled and
her smile made me terribly afraid. The thought that this thing which is
happening to me, this thing that I took to be a crime, may be only a
necessity—the thought fills me with horror! Am I in a prison? or is
this the cell of an insane asylum? Am I the victim of a villain? or am I
really mad? My pulse is quickening, but my memory is quite clear; I can
look back over every incident in my life.

"She has just taken away my food. I asked her to bring me only eggs as I
was afraid of everything else. She promised that she would do it.

"Are they looking for me? My guardian is Theodore Fellner, Cathedral Lane,
14. My own name is Asta Langen.

"They took away my travelling bag, but they did not find this little book
and the tiny bottle of perfume which I had in the pocket of my dress. And
I found this old pen and a little ink in a drawer of the writing table in
my room.

"Wednesday. The stranger was here again to-day. I recognised his soft
voice. He spoke to the woman in the hall outside my room. I listened, but
I could catch only a few words. 'To-morrow evening—I will come
myself—no responsibility for you.' Were these words meant for me?
Are they going to take me away? Where will they take me? Then they do not
dare to kill me here? My head is burning hot. I have not dared to drink a
drop of liquid for four days. I dare not take anything into which they
might have put some drug or some poison.

"Who could have such an interest in my death? It cannot be because of the
fortune which is to be mine when I come of age; for if I die, my father
has willed it to various charitable institutions. I have no relatives, at
least none who could inherit my money. I had never harmed any one; who can
wish for my death?

"There is somebody with her, somebody was listening at the door. I have a
feeling as if I was being watched. And yet—I examined the door, but
there is no crack anywhere and the key is in the lock. Still I seem to
feel a burning glance resting on me. Ah! the parrot! is this another
delusion? Oh God, let it end soon! I am not yet quite insane, but all
these unknown dangers around me will drive me mad. I must fight against
them.

"Thursday. They brought me back my travelling bag. My attendant is uneasy.
She was longer in cleaning up the room than usual to-day. She seemed to
want to say something to me, and yet she did not dare to speak. Is
something to happen to-day then? I did not close my eyes all night. Can
one be made insane from a distance? hypnotised into it, as it were? I will
not allow fear alone to make me mad. My enemy shall not find it too easy.
He may kill my body, but that is all—"

These were the last words which Asta Langen had written in her notebook,
the little book which was the only confidant of her terrible need. When
the detective had finished reading it, he closed his eyes for a few
minutes to let the impression made by the story sink into his mind.

Then he rose and put on his overcoat. He entered the commissioner's room
and took up his hat and cane.

"Where are you going, Muller?" asked Herr Von Mayringen.

"To Cathedral Lane, if you will permit it."

"At this hour? it is quarter past eleven! Is there any such hurry, do you
think? There is no train from any of our stations until morning. And I
have already sent a policeman to watch the house. Besides, I know that
Fellner is a highly respected man.

"There is many a man who is highly respected until he is found out,"
remarked the detective.

"And you are going to find out about Fellner?" smiled the commissioner.
"And this evening, too?"

"This very evening. If he is asleep I shall wake him up. That is the best
time to get at the truth about a man."

The commissioner sat down at his desk and wrote out the necessary
credentials for the detective. A few moments later Muller was in the
street. He left the notebook with the commissioner. It was snowing
heavily, and an icy north wind was howling through the streets. Muller
turned up the collar of his coat and walked on quickly. It was just
striking a quarter to twelve when he reached Cathedral Lane. As he walked
slowly along the moonlit side of the pavement, a man stepped out of the
shadow to meet him. It was the policeman who had been sent to watch the
house. Like Muller, he wore plain clothes.

"Well?" the latter asked.

"Nothing new. Mr. Fellner has been ill in bed several days, quite
seriously ill, they tell me. The janitor seems very fond of him.

"Hm—we'll see what sort of a man he is. You can go back to the
station now, you must be nearly frozen standing here."

Muller looked carefully at the house which bore the number 14. It was a
handsome, old-fashioned building, a true patrician mansion which looked
worthy of all confidence. But Muller knew that the outside of a house has
very little to do with the honesty of the people who live in it. He rang
the bell carefully, as he wished no one but the janitor to hear him.

The latter did not seem at all surprised to find a stranger asking for the
owner of the house at so late an hour. "You come with a telegram, I
suppose? Come right up stairs then, I have orders to let you in."

These were the words with which the old janitor greeted Muller. The
detective could see from this that Mr. Theodore Fellner's conscience must
be perfectly clear. The expected telegram probably had something to do
with the non-appearance of Asta Langen, of whose terrible fate her
guardian evidently as yet knew nothing. The janitor knocked on one of the
doors, which was opened in a few moments by an old woman.

"Is it the telegram?" she asked sleepily.

"Yes," said the janitor.

"No," said Muller, "but I want to speak to Mr. Fellner."

The two old people stared at him in surprise.

"To speak to him?" said the woman, and shook her head as if in doubt. "Is
it about Miss Langen?"

"Yes, please wake him."

"But he is ill, and the doctor—"

"Please wake him up. I will take the responsibility."

"But who are you?" asked the janitor.

Muller smiled a little at this belated caution on the part of the old man,
and answered. "I will tell Mr. Fellner who I am. But please announce me at
once. It concerns the young lady." His expression was so grave that the
woman waited no longer, but let him in and then disappeared through
another door. The janitor stood and looked at Muller with half
distrustful, half anxious glances.

"It's no good news you bring," he said after a few minutes.

"You may be right."

"Has anything happened to our dear young lady?"

"Then you know Miss Asta Langen and her family?"

"Why, of course. I was in service on the estate when all the dreadful
things happened."

"What things?"

"Why the divorce—and—but you are a stranger and I shouldn't
talk about these family affairs to you. You had better tell me what has
happened to our young lady."

"I must tell that to your master first."

The woman came back at this moment and said to Muller, "Come with me,
please. Berner, you are to stay here until the gentleman goes out again."

Muller followed her through several rooms into a large bed-chamber where
he found an elderly man, very evidently ill, lying in bed.

"Who are you?" asked the sick man, raising his head from the pillow. The
woman had gone out and closed the door behind her.

"My name is Muller, police detective. Here are my credentials."

Fellner glanced hastily at the paper. "Why does the police send to me?"

"It concerns your ward."

Fellner sat upright in bed now. He leaned over towards his visitor as he
said, pointing to a letter on the table beside his bed, "Asta's overseer
writes me from her estate that she left home on the 18th of November to
visit me. She should have reached here on the evening of the 18th, and she
has not arrived yet. I did not receive this letter until to-day."

"Did you expect the young lady?"

"I knew only that she would arrive sometime before the third of December.
That date is her twenty-fourth birthday and she was to celebrate it here."

"Did she not usually announce her coming to you?"

"No, she liked to surprise me. Three days ago I sent her a telegram asking
her to bring certain necessary papers with her. This brought the answer
from the overseer of her estate, an answer which has caused me great
anxiety. Your coming makes it worse, for I fear—" The sick man broke
off and turned his eyes on Muller; eyes so full of fear and grief that the
detective's heart grew soft. He felt Fellner's icy hand on his as the sick
man murmured: "Tell me the truth! Is Asta dead?"

The detective shrugged his shoulders. "We do not know yet. She was alive
and able to send a message at half past eight this evening."

"A message? To whom?"

"To the nearest police station." Muller told the story as it had come to
him.

The old man listened with an expression of such utter dazed terror that
the detective dropped all suspicion of him at once.

"What a terrible riddle," stammered the sick man as the other finished the
story.

"She has a fortune of over three hundred thousand guldens, and
considerable land."

"Has she any relatives?"

"No," replied Fellner harshly. But a thought must have flashed through his
brain for he started suddenly and murmured, "Yes, she has one relative, a
step-brother."

The detective gave an exclamation of surprise.

"Why are you astonished at this?" asked Fellner.

"According to her notebook, the young lady does not seem to know of this
step-brother."

"She does not know, sir. There was an ugly scandal in her family before
her birth. Her father turned his first wife and their son out of his house
on one and the same day. He had discovered that she was deceiving him, and
also that her son, who was studying medicine at the time, had stolen money
from his safe. What he had discovered about his wife made Langen doubt
whether the boy was his son at all. There was a terrible scene, and the
two disappeared from their home forever. The woman died soon after. The
young man went to Australia. He has never been heard of since and has
probably come to no good."

"Might he not possibly be here in Europe again, watching for an
opportunity to make a fortune?"

Fellner's hand grasped that of his visitor. The eyes of the two men gazed
steadily at each other. The old man's glance was full of sudden helpless
horror, the detective's eyes shone brilliantly. Muller spoke calmly: "This
is one clue. Is there no one else who could have an interest in the young
lady's death?"

"No one but Egon Langen, if he bear this name by right, and if he is still
alive."

"How old would he be now?"

"He must be nearly forty. It was many years before Langen married again."

"Do you know him personally?"

"Have you a picture of Miss Langen?"

Fellner rang a bell and Berner appeared. "Give this gentleman Miss Asta's
picture. Take the one in the silver frame on my desk;" the old gentleman's
voice was friendly but faint with fatigue. His old servant looked at him
in deep anxiety. Fellner smiled weakly and nodded to the man. "Sad news,
Berner! Sad news and bad news. Our poor Asta is being held a prisoner by
some unknown villain who threatens her with death."

"My God, is it possible? Can't we help the poor young lady?"

"We will try to help her, or if it is—too late, we will at least
avenge her. My entire fortune shall be given up for it. But bring her
picture now."

Berner brought the picture of a very pretty girl with a bright intelligent
face. Muller took the picture out of the frame and put it in his pocket.

"You will come again? soon? And remember, I will give ten thousand guldens
to the man who saves Asta, or avenges her. Tell the police to spare no
expense—I will go to headquarters myself to-morrow."

Fellner was a little surprised that Muller, although he had already taken
up his hat, did not go. The sick man had seen the light flash up in the
eyes of the other as he named the sum. He thought he understood this
excitement, but it touched him unpleasantly and he sank back, almost
frightened, in his cushions as the detective bent over him with the words
"Good. Do not forget your promise, for I will save Miss Langen or avenge
her. But I do not want the money for myself. It is to go to those who have
been unjustly convicted and thus ruined for life. It may give the one or
the other of them a better chance for the future."

"And you? what good do you get from that?" asked the old gentleman,
astonished. A soft smile illumined the detective's plain features and he
answered gently, "I know then that there will be some poor fellow who will
have an easier time of it than I have had."

He nodded to Fellner, who had already grasped his hand and pressed it
hard. A tear ran down his grey beard, and long after Muller had gone the
old gentleman lay pondering over his last words.

Berner led the visitor to the door. As he was opening it, Muller asked:
"Has Egon Langen a bad scar on his right cheek?"

Berner's eyes looked his astonishment. How did the stranger know this? And
how did he come to mention this forgotten name.

"Yes, he has, but how did you know it?" he murmured in surprise. He
received no answer, for Muller was already walking quickly down the
street. The old man stared after him for some few minutes, then suddenly
his knees began to tremble. He closed the door with difficulty, and sank
down on a bench beside it. The wind had blown out the light of his
lantern; Berner was sitting in the dark without knowing it, for a sudden
terrible light had burst upon his soul, burst upon it so sharply that he
hid his eyes with his hands, and his old lips murmured, "Horrible!
Horrible! The brother against the sister."

The next morning was clear and bright. Muller was up early, for he had
taken but a few hours sleep in one of the rooms of the station, before he
set out into the cold winter morning. At the next corner he found Amster
waiting for him. "What are you doing here?" he asked in astonishment.

"I have been thinking over what you said to me yesterday. Your profession
is as good and perhaps better than many another."

"And you come out here so early to tell me that?"

Amster smiled. "I have something else to say."

"Well?"

"The commissioner asked me yesterday if I knew of a church in the city
that had a slender spire with a green top and two poplars in front of it."

Muller looked his interest.

"I thought it might possibly be the Convent Church of the Grey Sisters,
but I wasn't quite sure, so I went there an hour ago. It's all right, just
as I thought. And I suppose it has something to do with the case of last
night, so I thought I had better report at once. I was on my way to the
station."

"That will do very well. You have saved us much time and you have shown
that you are eminently fitted for this business."

"If you really will try me, then—"

"We'll see. You can begin on this. Come to the church with me now." Muller
was no talker, particularly not when, as now, his brain was busy on a
problem.

The two men walked on quickly. In about half an hour they found themselves
in a little square in the middle of which stood an old church. In front of
the church, like giant sentinels, stood a pair of tall poplars. One of
them looked sickly and was a good deal shorter than its neighbour. Muller
nodded as if content.

"Is this the church the commissioner was talking about?" queried Amster.

"It is," was the answer. Muller walked on toward a little house built up
against the church, which was evidently the dwelling of the sexton.

The detective introduced himself to this official, who did not look
over-intelligent, as a stranger in the city who had been told that the
view from the tower of the church was particularly interesting. A bright
silver piece banished all distrust from the soul of the worthy man. With
great friendliness he inquired when the gentlemen would like to ascend the
tower. "At once," was the answer.

The sexton took a bunch of keys and told the strangers to follow him. A
few moments later Muller and his companion stood in the tiny belfry room
of the slender spire. The fat sexton, to his own great satisfaction, had
yielded to their request not to undertake the steep ascent. The cloudless
sky lay crystal clear over the still sleeping city and the wide spread
snow-covered fields which lay close at hand, beyond the church. On the one
side were gardens and the low rambling buildings of the convent, and on
the other were huddled high-piled dwellings of poverty.

Muller looked out of each of the four windows in turn. He spent some time
at each window, but evidently without discovering what he looked for, for
he shook his head in discontent. But when he went once more to the opening
in the East, into which the sun was just beginning to pour its light,
something seemed to attract his attention. He called Amster and pointed
from the window. "Your eyes are younger than mine, lend them to me. What
do you see over there to the right, below the tall factory chimney?"
Muller's voice was calm, but there was something in his manner that
revealed excitement. Amster caught the infection without knowing why. He
looked sharply in the direction towards which Muller pointed, and began:
"There is a tall house near the chimney, to the right of it, one wall
touching it. The house is crowded in between other newer buildings, and
looks to be very old and of a much better sort than its neighbours. The
other houses are plain stone, but this house has carvings and statues on
it, which are white with snow. But the house is in bad condition, one can
see cracks in the wall."

"And its windows?"

"I cannot see them. They must be on the other side of the house, towards
the courtyard which seems to be hemmed in by the blank walls of the other
houses."

"And at the front of the house?"

"There is a low wall in front which shuts off the courtyard from a narrow,
ill-kept street."

"Yes, I see it myself now. The street is bordered mainly by gardens and
vacant lots."

"Yes, sir, that is it." Muller nodded as if satisfied. Amster looked at
him in surprise, still more surprised, however, at the excitement he felt
himself. He did not understand it, but Muller understood it. He knew that
he had found in Amster a talent akin to his own, one of those natures who
once having taken up a trail cannot rest until they reach their goal. He
looked for a few moments in satisfaction at the assistant he had found by
such chance, then he turned and hastened down the stairs again.

"We're going to that house?" asked Amster when they were down in the
street. Muller nodded.

Without hesitation the two men made their way through a tangle of dingy,
uninteresting alleys, between modern tenements, until about ten minutes
later they stood before an old three-storied building, which had a
frontage of four windows on the street. "This is our place," said the
detective, looking up at the tall, handsome gateway and the rococo
carvings that ornamented the front of this decaying dwelling. It was very
evidently of a different age and class from those about it.

Muller had already raised his hand to pull the bell, when he stopped and
let it sink again. His eye caught sight of a placard pasted up on the wall
of the next house, and already half torn off by the wind. The detective
walked over, and raising the placard with his cane, read the words on it.
"That's right," he said to himself. Amster gave a look on the paper. But
he could not connect the contents of the notice with the case of the
kidnapped lady, and he shook his head in surprise when Muller turned to
him with the words: "The lady we are looking for is not insane." On the
paper was announced in large letters that a reward would be offered to the
finder of a red and green parrot which had escaped from a neighbouring
house.

Muller rang the bell and they had to wait some few minutes before the door
opened with great creakings, and the towsled head of an old woman peered
out.

"What do you want?" she asked hoarsely, with distrustful looks.

"Let us in, and then give us the keys of the upstairs rooms." Muller's
voice was friendly, but the woman grew perceptibly paler.

"Who are you?" she stammered. Muller threw back his overcoat and showed
her his badge. "But there is nobody here, the house is quite empty."

"There were a lady and gentleman here last evening." The woman threw a
frightened look at Muller, then she said hesitatingly: "The lady was
insane and has been taken to an asylum."

"That is what the man told you. He is a criminal and the police are
looking for him."

"Come with me," murmured the woman. She seemed to understand that further
resistance was useless. She carefully locked the outside door. Amster
remained down stairs in the corridor, while Muller followed the old woman
up the stairs. The staircase to the third story was made of wood. The
house was evidently very old, with low ceilings and many dark corners.

The woman led Muller into the room in which she had cared for the strange
lady at the order of the latter's "husband." He had told her that it was
only until he could take the lady to an asylum. One look at the wall
paper, a glance out of the window, and Muller knew that this was where
Asta Langen had been imprisoned. He sat down on a chair and looked at the
woman, who stood frightened before him.

"Do you know where they have taken the lady?"

"No, sir.

"Do you know the gentleman's name?"

"No, sir.

"You did not send the lady's name to the authorities?" *

"No, sir."

* Any stranger taking rooms in a hotel or lodging house must
be registered with the police authorities by the proprietor
of the house within forty-eight hours of arrival.

"Were you not afraid you would get into trouble?"

"The gentleman paid me well, and I did not think that he meant anything
bad, and—and—"

"And you did not think that it would be found out?" said Muller sternly.

"I took good care of the lady."

"Yes, we know that."

"Did she escape from her husband?"

"He was not her husband. But now tell me all you know about these people;
the more truthful you are the better it will be for you."

The old woman was so frightened that she could scarcely find strength to
talk. When she finally got control of herself again she began: "He came
here on the first of November and rented this room for himself. But he was
here only twice before he brought the lady and left her alone here. She
was very ill when he brought her here—so ill that he had to carry
her upstairs. I wanted to go for a doctor, but he said he was a doctor
himself, and that he could take care of his wife, who often had such
attacks. He gave me some medicine for her after I had put her to bed. I
gave her the drops, but it was a long while before she came to herself
again.

"Then he told me that she had lost her mind, and that she believed
everybody was trying to harm her. She was so bad that he was taking her to
an asylum. But he hadn't found quite the right place yet, and wanted me to
keep her here until he knew where he could take her. Once he left a
revolver here by mistake. But I hid it so the lady wouldn't see it, and
gave it to the gentleman the next time he came. He was angry at that,
though I couldn't see why, and said I shouldn't have touched it."

The woman had told her story with much hesitation, and stopped altogether
at this point. She had evidently suddenly realised that the lady was not
insane, but only in great despair, and that people in such a state will
often seek death, particularly if any weapon is left conveniently within
their reach.

"What did this gentleman look like?" asked Muller, to start her talking
again. She described her tenant as very tall and stout with a long beard
slightly mixed with grey. She had never seen his eyes, for he wore smoked
glasses.

"Did you notice anything peculiar about his face?"

"No, nothing except that his beard was ver heavy and almost covered his
face."

"Could you see his cheeks at all?"

"No, or else I didn't notice."

"Did he leave nothing that might enable us to find him?"

"No, sir, nothing. Or yes, perhaps, but I don't suppose that will be any
good."

"What was it? What do you mean?"

"It gave him a good deal of trouble to get the lady into the wagon,
because she had fainted again. He lost his glove in doing it. I have it
down stairs in my room, for I sleep down stairs again since the lady has
gone."

Muller had risen from his chair and walked over to the old writing desk
which stood beside one window. There were several sheets of ordinary brown
paper on it and sharp pointed pencil and also something not usually found
on writing desks, a piece of bread from which some of the inside had been
taken. "Everything as I expected it," he said to himself. "The young lady
made up the package in the last few moments that she was left alone here."

He turned again to the old woman and commanded her to lead him down
stairs. "What sort of a carriage was it in which they took the lady away?"
he asked as they went down.

"A closed coupe."

"Did you see the number?"

"No, sir. But the carriage was very shabby and so was the driver."

"Was he an old man?"

"He was about forty years old, but he looked like a man who drank. He had
a light-coloured overcoat on."

"Good. Is this your room?"

"Yes, sir."

They were now in the lower corridor, where they found Amster walking up
and down. The woman opened the door of the little room, and took a glove
from a cupboard. Muller put it in his pocket and told the woman not to
leave the house for anything, as she might be sent for to come to the
police station at any moment. Then he went out into the street with
Amster. When they were outside in the sunlight, he looked at the glove. It
was a remarkably small size, made for a man with a slender, delicate hand,
not at all in accordance with the large stout body of the man described by
the landlady. Muller put his hand into the glove and found something
pushed up into the middle finger. He took it out and found that it was a
crumpled tramway ticket.

"Look out for a shabby old closed coupe, with a driver about forty years
old who looks like a drunkard and wears a light overcoat. If you find such
a cab, engage it and drive in it to the nearest police station. Tell them
there to hold the man until further notice. If the cab is not free, at
least take his number. And one thing more, but you will know that
yourself,—the cab we are looking for will have new glass in the
right-hand window." Thus Muller spoke to his companion as he put the glove
into his pocket and unfolded the tramway ticket. Amster understood that
they had found the starting point of the drive of the night before.

"I will go to all coupe stands," he said eagerly.

"Yes, but we may be able to find it quicker than that." Muller took the
little notebook, which he was now carrying in his pocket, and took from it
the tramway ticket which was in the cover. He compared it with the one he
had just found. They were both marked for the same hour of the day and for
the same ride.

"Did the man use them?" asked Amster. The detective nodded. "How can they
help us?"

"Somewhere on this stretch of the street railroad you will probably find
the stand of the cab we are looking for. The man who hired it evidently
arrived on the 6:30 train at the West Station—I have reason to
believe that he does not live here,—and then took the street car to
this corner. The last ticket is marked for yesterday. In the car he
probably made his plans to hire a cab. So you had better stay along the
line of the car tracks. You will find me in room seven, Police
Headquarters, at noon to-day. The authorities have already taken up the
case. You may have something to tell us then. Good luck to you."

Muller hurried on, after he had taken a quick breakfast in a little cafe.
He went at once to headquarters, made his report there and then drove to
Fellner's house. The latter was awaiting him with great impatience. There
the detective gathered much valuable information about the first marriage
of Asta Langen's long-dead father. It was old Berner who could tell him
the most about these long-vanished days.

When he reached his office at headquarters again, he found telegrams in
great number awaiting him. They were from all the hospitals and insane
asylums in the entire district. But in none of them had there been a
patient fitting the description of the vanished girl. Neither the
commissioner nor Muller was surprised at this negative result. They were
also not surprised at all that the other branches of the police department
had been able to discover so little about the disappearance of the young
lady. They were aware that they had to deal with a criminal of great
ability who would be careful not to fall into the usual slips made by his
kind.

There was no news from the cab either, although several detectives were
out looking for it. It was almost nightfall when Amster ran breathlessly
into room number seven. "I have him! he's waiting outside across the way!"
This was Amster's report.

Muller threw on his coat hastily. "You didn't pay him, did you? On a cold
day like this the drivers don't like to wait long in any one place."

"No danger. I haven't money enough for that," replied Amster with a sad
smile. Muller did not hear him as he was already outside. But the
commissioner with whom he had been talking and to whom Muller had already
spoken of his voluntary assistant, entered into a conversation with
Amster, and said to him finally: "I will take it upon myself to guarantee
your future, if you are ready to enter the secret service under Muller's
orders. If you wish to do this you can stay right on now, for I think we
will need you in this case."

Amster bowed in agreement. His life had been troubled, his reputation
darkened by no fault of his own, and the work he was doing now had
awakened, an interest and an ability that he did not know he possessed. He
was more than glad to accept the offer made by the official.

Muller was already across the street and had laid his hand upon the door
of the cab when the driver turned to him and said crossly, "Some one else
has ordered me. But I am not going to wait in this cold, get in if you
want to."

"All right. Now tell me first where you drove to last evening with the
sick lady and her companion?" The man looked astonished but found his
tongue again in a moment. "And who are you?" he asked calmly.

"We will tell you that upstairs in the police station," answered Muller
equally calmly, and ordered the man to drive through the gateway into the
inner courtyard. He himself got into the wagon, and in the course of the
short drive he had made a discovery. He had found a tiny glass stopper,
such as is used in perfume bottles. He could understand from this why the
odour of perfume which had now become familiar to him was still so strong
inside the old cab. Also why it was so strong on the delicate
handkerchief. Asta Langen had taken the stopper from the bottle in her
pocket, so as to leave a trail of odour behind her.

CHAPTER THREE. THE LONELY COTTAGE

Fifteen minutes after the driver had made his report to Commissioner Von
Mayringen, the latter with Amster entered another cab. A well-armed
policeman mounted the box of this second vehicle. "Follow that cab ahead,"
the commissioner told his driver. The second cab followed the one-horse
coupe in which Muller was seated. They drove first to No. 14 Cathedral
Lane, where Muller told Berner to come with him. He found Mr. Fellner
ready to go also, and it was with great difficulty that he could dissuade
the invalid, who was greatly fatigued by his morning visit to the police
station, from joining them.

The carriages then drove off more quickly than before. It was now quite
dark, a gloomy stormy winter evening. Muller had taken his place on the
box of his cab and sat peering out into the darkness. In spite of the
sharp wind and the ice that blew against his face the detective could see
that they were going out from the more closely built up portions of the
city, and were now in new streets with half-finished houses. Soon they
passed even these and were outside of the city. The way was lonely and
dreary, bordered by wooden fences on both sides. Muller looked sharply to
right and to left.

"You should have become alarmed here," he said to the driver, pointing to
one part of the fence.

"Why?" asked the man.

"Because this is where the window was broken."

"I didn't know that—until I got home."

"H'm; you must have been nicely drunk."

The driver murmured something in his beard.

"Stop here, this is your turn, down that street," Muller said a few
moments later, as the driver turned the other way.

"How do you know that?" asked the man, surprised.

"None of your business."

"This street will take us there just the same."

"Probably, but I prefer to go the way you went yesterday."

"Very well, it's all the same to me." They were silent again, only the
wind roared around them, and somewhere in the distance a fog horn moaned.

It was now six o'clock. The snow threw out a mild light which could not
brighten the deep darkness around them. About half an hour later the first
cab halted. "There's the house up there. Shall I drive to the garden
gate?"

"No, stop here." Muller was already on the ground. "Are there any dogs
here?" he asked.

"I didn't hear any yesterday."

"That's of no value. You didn't seem to hear much of anything yesterday."
Muller opened the door of the cab and helped Berner out. The old man was
trembling. "That was a dreadful drive!" he stammered.

"I hope you will be happier on the drive back," said the detective and
added, "You stay here with the commissioner now."

The latter had already left his cab with his companion. His sharp eyes
glanced over the heavily shaded garden and the little house in its midst.
A little light shone from two windows of the first story. The men's eyes
looked toward them, then the detective and Amster walked toward a high
picket fence which closed the garden on the side nearest its neighbours.
They shook the various pickets without much caution, for the wind made
noise enough to kill any other sound. Amster called to Muller, he had
found a loose picket, and his strong young arms had torn it out easily.
Muller motioned to the other three to join them. A moment later they were
all in the garden, walking carefully toward the house.

The door was closed but there were no bars at the windows of the ground
floor. Amster looked inquiringly at the commissioner and the latter nodded
and said, "All right, go ahead."

The next minute Amster had broken in through one pane of the window and
turned the latch. The inner window was broken already so that it was not
difficult for him to open it without any further noise. He disappeared
into the dark room within. In a few seconds they heard a key turn in the
door and it opened gently. The men entered, all except the policeman, who
remained outside. The blind of his lantern was slightly opened, and he had
his revolver ready in his hand.

Muller had opened his lantern also, and they saw that they were in a
prettily furnished corridor from which the staircase and one door led out.

The four men tiptoed up the stairway and the commissioner stepped to the
first of the two doors which opened onto the upper corridor. He turned the
key which was in the lock, and opened the door, but they found themselves
in a room as dark as was the corridor. From somewhere, however, a ray of
light fell into the blackness. The official stepped into the room, pulling
Berner in after him. The poor old man was in a state of trembling
excitement when he found himself in the house where his beloved young lady
might already be a corpse. One step more and a smothered cry broke from
his lips. The commissioner had opened the door of an adjoining room, which
was lighted and handsomely furnished. Only the heavy iron bars across the
closed windows showed that the young lady who sat leaning back wearily in
an arm-chair was a prisoner.

She looked up as they entered. The expression of utter despair and deep
weariness which had rested on her pale face changed to a look of terror;
then she saw that it was not her would-be murderer who was entering, but
those who came to rescue. A bright flush illumined her cheeks and her eyes
gleamed. But the change was too sudden for her tortured soul. She rose
from her chair, then sank fainting to the floor.

Berner threw himself on his knees beside her, sobbing out, "She is dying!
She is dying!"

Muller turned on the instant, for he had heard the door on the other side
of the hall open, and a tall slender man with a smooth face and a deep
scar on his right cheek stood on the threshold looking at them in dazed
surprise. For an instant only had he lost his control. The next second he
was in his room again, slamming the door behind him. But it was too late.
Amster's foot was already in the crack of the door and he pushed it open
to let Muller enter. "Well done," cried the latter, and then he turned to
the man in the room. "Here, stop that. I can fire twice before you get the
window open."

The man turned and walked slowly to the centre of the room, sinking down
into an arm-chair that stood beside the desk. Neither Amster nor Muller
turned their eyes from him for a moment, ready for any attempt on his part
to escape. But the detective had already seen something that told him that
Langen was not thinking of flight. When he turned to the desk, Muller had
seen his eyes glisten while a scornful smile parted his thin, lips. A
second later he had let his handkerchief fall, apparently carelessly, upon
the desk. But in this short space of time the detective's sharp eyes had
seen a tiny bottle upon which was a black label with a grinning skull.
Muller could not see whether the bottle was full or empty, but now he knew
that it must hold sufficient poison to enable the captured criminal to
escape open disgrace. Knowing this, Muller looked with admiration at the
calmness of the villain, whose intelligent eyes were turned towards him in
evident curiosity.

"Who are you and who else is here with you?" asked the man calmly.

"I am Muller of the Secret Service," replied his visitor and added, "You
must put up with us for the time being, Mr. Egon Langen. The police
commissioner is occupied with your step-sister, whom you were about to
murder."

Langen put his hand to his cheek, looking at Muller between his lashes as
he said, "To murder? Who can prove that?"

"We have all the proofs we need."

"I will acknowledge only that I wanted Asta to disappear."

Muller smiled. "What good would that have done you? You wanted her entire
fortune, did you not? But that could have come to you only after thirty
years, and you are not likely to have waited that long. Your plan was to
murder your step-sister, even if you could not get a letter from her
telling of her intention to commit suicide."

Langen rose suddenly, but controlled himself again and sank back easily in
his chair. "Then the old woman has been talking?" he asked.

Muller shook his head. "We knew it through Miss Langen herself."

"She has spoken to no one for over ten days."

"But you let her throw her notebook out of the window of the cab."

"Ah—"

"There, you see, you should not have let that happen."

Drops of perspiration stood out on Langen's forehead. Until now, perhaps,
he had had some possible hope of escape. It was useless now, he knew.

As calmly as he had spoken thus far Muller continued. "For twenty years I
have been studying the hearts of criminals like yourself. But there are
things I do not understand about this case and it interests me very much."

Langen had wiped the drops from his forehead and he now turned on Muller a
face that seemed made of bronze. There was but one expression on it, that
of cold scorn.

"I feel greatly flattered, sir, to think that I can offer a problem to one
of your experience," Langen began. His voice, which had been slightly
veiled before, was now quite clear. "Ask me all you like. I will answer
you."

Muller began: "Why did you wait so long before committing the murder? and
why did you drag your victim from place to place when you could have
killed her easily in the compartment of the railway train?"

"The windows of the compartment were open, my honoured friend, and it was
a fine warm evening for the season, because of which the windows in the
other compartment were also open. There was nothing else I could do at
that time then, except to offer Asta a cup of tea when she felt a little
faint upon leaving the train. I am a physician and I know how to use the
right drugs at the right time. When Asta had taken the tea, she knew
nothing more until she woke up a day later in a room in the city."

"And the piece of paper with the threat on it? and the revolver you left
so handy for her? oh, but I forgot, the old woman took the weapon away
before the lady could use it in her despair," said Muller.

"Quite right. I see you know every detail."

"But why didn't you complete your crime in the room in the old house?"
persisted Muller.

"Because I lost my false beard one day upon the staircase, and I feared
the old woman might have seen my face enough to recognise me again. I
thought it better to look for another place."

"And then you found this house."

"Yes, but several days later."

"And you hired it in the name of Miss Asta Langen? Who would then have
been found dead here several days after you had entered the house?"

"Several days, several weeks perhaps. I preferred to wait until the woman
who rented the house had read in the papers that Asta Langen had
disappeared and was being sought for. Somebody would have found her here,
and her identity would have easily been established, for I knew that she
had some important family documents with her."

Muller was silent a moment, with an expression of deep pity on his face.
Then he continued: "Yes, someone would have found her, and her suicide
would have been a dark mystery, unless, of course, malicious tongues would
have found ugly reasons enough why a beautiful young lady should hide
herself in a lonely cottage to take her own life."

Muller had spoken as if to himself. Egon Langen's lips, parted in a smile
so evil that Amster clenched his fists.

"And you would not have regretted this ruining the reputation as well as
taking the life of an innocent girl?" asked the detective low and tense.

"No, for I hated her."

"You hated her because she was rich and innocent. She was very charitable
and would gladly have helped you if you were in need. Beside this, you
were entitled to a portion of your father's estate. It is almost thirty
thousand guldens, as Mr. Fellner tells me. Why did you not take that?"

"Fellner did not know that I had already received twenty thousand of this
when my father turned me out. He probably would have heard of it later,
for Berner was the witness. I did not care for the remaining ten thousand
because I would have the entire fortune after Asta's death. I would have
seen the official notice and the call for heirs in Australia, and would
have written from there, announcing that I was still alive. If you had
come several days later I should have been a rich man within a year."

His clenched fist resting on his knee, the rascal stared out ahead of him
when he ended his shameless confession. In his rage and disappointment he
had not noticed that Muller's hand dropped gently to the desk and softly
took a little bottle from under the handkerchief. Langen came out of his
dark thoughts only when Muller's voice broke the silence. "But you
miscalculated, if you expected to inherit from your sister. She is still a
minor and your father's will would have given you only ten thousand
guldens.

"But you forget that Asta will be twenty-four on the third of December."

"Ah, then you would have kept her alive until then."

"You understand quickly," said Langen with a mocking smile.

"But she disappeared on the eighteenth of November. How could you prove
that she died after her birthday, therefore in full possession of her
fortune and without leaving any will?"

"That is very simple. I buy several newspapers every day. I would have
taken them up to the fourth and fifth of December and left them here with
the body."

"You are more clever even than I thought," said the detective dryly as he
heard the commissioner's steps behind him. Muller put a whistle to his
lips and its shrill tone ran through the house, calling up the policeman
who stood by the door.

Egon Langen's face was grey with pallor, his features were distorted, and
yet there was the ghost of a smile on his lips as he saw his captors enter
the door. He put his hand out, raised his handkerchief hastily and then a
wild scream echoed through the room, a scream that ended in a ghastly
groan.

"I have taken your bottle, you might as well give yourself up quietly,"
said Muller calmly, holding his revolver near Langen's face. The prisoner
threw himself at the detective but was caught and overpowered by Amster
and the policeman.

A quarter of an hour later the cabs drove back toward the city. Inside one
cowered Egon Langen, watched by the policeman and Amster. Berner was on
the box beside the driver, telling the now interested man the story of
what had happened to his dear young lady. In the other cab sat Asta Langen
with Kurt von Mayringen and Muller.

"Do you feel better now?" asked the young commissioner in sincere sympathy
that was mingled with admiration for the delicate beauty of the girl
beside him, an admiration heightened by her romantic story and marvelous
escape.

Asta nodded and answered gently: "I feel as if some terrible weight were
lifted from my heart and brain. But I doubt if I will ever forget these
horrible days, when I had already come to accept it as a fact that—that
I was to be murdered."

"This is the man to whom you owe your escape," said the commissioner,
laying his hand on Muller's knee. Asta did not speak, but she reached out
in the darkness of the cab, caught Muller's hand and would have raised it
to her lips, had not the little man drawn it away hastily. "It was only my
duty, dear young lady," he said. "A duty that is not onerous when it means
the rescue of innocence and the preventing of crime. It is not always so,
unfortunately—nor am I always so fortunate as in this case."

This indeed is what Muller calls a "case with a happy ending," for
scarcely a year later, to his own great embarrassment, he found himself
the most honoured guest, and a centre of attraction equally with the
bridal couple, at the marriage of Kurt von Mayringen and Asta Langen.
Muller asserts, however, that he is not a success in society, and that he
would rather unravel fifty difficult cases than again be the "lion" at a
fashionable function.
